Tablet PC, also known as industrial contact tablet PC, is an inductive LCD display device that can transmit keying signals such as auxiliary contacts, when touching the graphic buttons on the display screen, the haptic feedback system on the display screen can drive various connected devices according to the pre-programmed program, which can be used to replace the mechanical machine-type button control panel, and produce vivid audio-visual effects through the LCD screen.
Question 1: Why does my all-in-one conference machine have contact in some places and some don't?
Reason 1: Infrared contact is sent while transmitting, in the middle of the finger or pen to click on the display screen will immediately produce a point of disconnection contact, generally the inside of the contact frame around the object blocking or more dust will lead to a part of the poor contact; Make sure there are no obstructions in the contact frame and clean the displayGive it a try.
Reason 2: The destruction of some infrared transmitting lamps can be detected by contacting the manufacturer's software.
Question 2: Why is my industrial contact tablet PC contactless?
Full-screen contactless inspection method:
The contact wire of the computer motherboard of the industrial contact tablet computer is plugged in backwards. It is necessary to see whether the contact wire is plugged in at the end of the contact frame, and check whether the contact wire at this end of the computer motherboard is reversed; The contact wire can be directly burned off, and it will also cause the full screen to be contactless. Subsequently, it can also be caused by contacting the manufacturer's software.
The best way to encounter problems in the application of industrial contact tablet computers is to call the manufacturer, and they can't blindly disassemble the machine independently.

The driving principle of a capacitive touch screen
1. Projective capacitive contacts
Although the basic structure and operating principle of the projection capacitive contact screen is the same as that of the four-wire impedance film, the projection capacitive impedance film does not pass through the contact field, but captures the change of capacitance between the electrodes. Generally speaking, when using the form of capacitive sensor, it can almost ...
